Helicopter-borne Electromagnetics (HEM) Area 124 Stassfurt
Description
BGR conducted an airborne survey in the region of the Stassfurt-Egeln salt anticline as part of a BMBF research project "Dynamic processes in flooded or abandoned salt mines and their overburden”. The survey area Stassfurt (2007) is bounded by the towns and settlements Aschersleben, Kroppenstedt, Hadmersleben, Altenweddingen, Atzendorf, Förderstedt and Bernburg. The size of the area is about 467 km². The area was surveyed with 29 flights totalling 5137 line-km (1,344,787 survey points). The nominal separation of the 197 SE-NW lines and 39 NE-SW tie lines was 100 m and 1000 m, respectively. The maps display the geophysical parameters apparent resistivity and centroid depth derived from the HEM data at the six frequencies of the HEM system (0.4 - 133 kHz). Furthermore, horizontal and vertical slices were derived from layered-earth models (resistivities and thicknesses of four model layers).
